Having thus described my invention, what i claim as new and desire to secure by Lett ters Patent is:

In mechanism of the class described, in combination, a plurality of printing couples spaced apart from one another and each sion cylinder, the axes of revolution of the several cylinders being in parallel relation toone another, and the distance between the axes of the form cylinders being less than the distance between the axes of the inipression cylinders mechanism arranged intermediate said printing couples adapted to receive and change the direction of feed of a web, whereby the same will be received between the first oi said print ing couples to receive printed impressions upon one side thereof, a roller arranged intermediate said printingcouples adapted to receive and guide the web from the first of said couples, said roller being located adjacent the second of said couples, a second roller adjacent said second couple and adapted to receive the web from said first roller to guide the same to said second printing couple whereby the opposite side of the web will receive printed impressions, common inking means for said printing couples located intermediate the same. and an accumulating roll upon which said web is adapted to be wound after passing through said second printing couple.

In testimony whereof i atlix my signature, in the presence of two witnesses.
